I have tried all other Ubuntu versions, e.g 15.10, 14.04 LTS, Kubuntu,
and the latest 16.04 LTS testing image, but it still has the same wifi
problem:  Intel 7260 Wifi does not work. I have also tried to copy
firmware from Intel website to /lib/firmware, but it still has the same
problem.

I think this issue is very urgent now, because the Intel 7260 is very
common.

THanks a lot for your kind helps.
